Total Surface Area Calculation
To find the total cost of painting the cuboidal boxes, we first need to calculate the surface area of one box.
- Dimensions of one box: 60 cm x 45 cm x 30 cm
- Formula for surface area of a cuboid:
Surface Area = 2(lw + lh + wh)
where l = length, w = width, h = height.
- Calculating each area:
- lw = 60 cm * 45 cm = 2700 cm²
- lh = 60 cm * 30 cm = 1800 cm²
- wh = 45 cm * 30 cm = 1350 cm²
- Total surface area of one box:
Surface Area = 2(2700 + 1800 + 1350)
= 2 * 5850 cm²
= 11700 cm²
Conversion to Square Metres
Since the painting rate is given per square metre, we need to convert the area from square centimetres to square metres.
- Conversion:
1 m² = 10,000 cm²
Total Surface Area in m² = 11700 cm² / 10,000 = 1.17 m²
Total Surface Area for 8 Boxes
Now, we will calculate the total surface area for 8 boxes.
- Total surface area for 8 boxes:
Total Area = 8 * 1.17 m² = 9.36 m²
Cost Calculation
Finally, we can calculate the total cost of painting.
- Painting rate: Rs 200 per m²
- Total Cost:
Total Cost = 9.36 m² * 200 Rs/m² = Rs 1872
Final Result
Therefore, the total cost of painting the 8 cuboidal boxes is Rs 1872.
